ISSR Analysis of Genetic Diversity for 44 Oriental Tobacco Cultivars
摘要
Abstract
ISSR analysis was conducted to estimate the degree of genetic diversity for the 44 oriental tobacco cultivars. The results showed that the 8 primers, which selected from 100 ISSR primers, generated 223 fragments, of which 209 fragments were polymorphic. The genetic similarity coefficient among all materials was distributed from 0.51 to 0.96, average 0.79. The 44 oriental tobacco cultivars was divided into 2 types by a similarity coefficient 0.636. Two major distinct clusters were discovered by using UPGMA methods. And great efforts should be made to broaden genetic diversity of oriental tobacco by germplasm introduction and innovation.关键词
